Specication of Letters Patent. y

Patented Mar. s, 1910.l

To alt whom it may conloem:

Be itknown that we, ZoLTAN B. Csrnr, 'T Aco KRONELEIM, and ZoLTAN TAM'Assv, residing atCleveland, in the ooh invented certain new and useful Improvements in Conrtible Chairs, of which the following is a specification.

Our invention relates to convertible chairs,

and is'an improvement in that' class of vchairs wherein the seat and back of the chair lis inverted to form a bed, all as hereinafter` described and more particularly pointed out 1n the claims. i

5 In the accompanying drawings, Figure l is a 4perspective view ofthe chair when folded, and Fig. 2 is a vertical section thereof showing the springs` and bed `mattress particularly. Fig. 3 is a vertical ,section on line .1v-m, Fig. 4, and Fig. 4 is a sectional view on line 'zyy, Fig. 3 -showing the skeleton frame more particularly and with theV upholstering springs and mattress removed. Fig. 5 is a plan view of the frame parts unfolded for use as a bed and with the side arms lowered and broken away in part,` and 6 is a longitudinal section centrally of Our linvention comprises -an open base frame -2- of rectangular or square formation supported by legs --3-A at its four corners, and the yside pieces -4; of said frame are preferably and approximately double the height of crosspieces 54. An' open seatframe 6- corresponding in size and shape to base frame -2-, is hinged at -7- to the front end of side pieces Llthereby permitting said seat frame to either' rest Hush upon base frame Q-f, or be inverted 40 to the samehorizontalplane at the front thereof. `lhen .inverted cross piece --8- of seat frane'j-GQ- abuts against front cross piece -5- ofbase ,frame -2- to maintain horizontal alinement between said frames. -A

4l-f, respectively, are adapted to stand upright in more or less lparallel relationship tok jointly form the back of the chair.,

To Vdistinguish between. these two back nty of Cuya-l freedom for the occupant 'o frames, frame 9 will behereinafter referred horizontal plane as shown 1n Fig.j6. In so z doing a pair of legs +13- pivotallymounted inside yrecesses i4-.- on seat back 9 are caused to drop by gravity to avertical supporting position for seatback l-f9-, and

a' similar pair of legs (not shown) may be used fore seat frame 6 if desired, but the shouldered joint at hinges --10- is deemed sufficient to produce .a rigid supporting frame for the purposes required. p

Hinged back rest ,-1lis adjustably supported at different inclinations by a curved ratchet link -15 pivotally secured to cross piece -i6-- of the restframe, and

-which link is adapted to lockingly engage slotted keeper. 17- fastened to the rear face of cross piece -5-1of base frame ,-2-. A. cable 1S- attached to linke-'15- ex` tends to an operating lever '-'19- `pivotally mounted to the upper cross piece e-20- of back rest- -ll-e, and which lever is provided with a button or stem -2ladapted to project through an opening in said cross piece and where it may be engaged and de` pressed by .the finger or hand to lift' link -l5- free of keeper -fl7- and permitV raising or lowering of back rest -11- to any desired inclination.' Link y--15- may either `lock by gravity orbe spring pressed` to the same end.

A further feature of the invention is embodied in. the drop side arms .-22-f at either side thereof, and ,which are lowered to a horizontal lane when the parts are unfolded to form a ed.` Thus, each arm -22- is'preferably smooth and. plainlts full height and lenth on .the inside :tace` thereof ywhere it 'aabuts and reshts Hush against the sides' of the frameparts, so that -when said arms are lowered each may provide a table `or stand at either side of the Yhed at the head thereof. In addition, the

lowering ofv said" side arms 1pinail'jtesC-lgreterf e an v1 novother` advantage were afforded by their l use, this alnegwould vbe noteworthy.

Lowering and raising of-arms -`22.'- is' obtained-by a pairof cables 24 and 25, re-z spectively, afset for each at 'either side ofy base. frame -2 Each cable '-24- conel rigidly affixed to eacharm -,-22-- and eX- tending downwardly. and vinwardly beneath hinges -23-, there-'being' anopening -1-28-4 provided therefor, at'tlie bottom ofside pieces -4 The other end-of -each cable--2 after passing over a sheave -29- is attached. at pointsfBO- onthe linside of'jseat frame- '-'-6-" and relatively near `to the'pivotal point of hinge -7 so However, this lowering 'of the vside armsis not immediate, there being a relatively greater and faster movement of seat frame' 6 at its free end than I where cable -24 `is attached at point 30", and the natural slack in .the cable must also'be taken 'up before an actual pull is hadupo'n projec- Thisv gives -an interval of rest for the side arms during initial 'unfolding `of seat frame f5- which is taken advantage. of to disengage two locking hookmembers .-land -32-, mounted on` vffs'pectively, see Fig. 3.v Said hooks 4pivotally lock the side arms to the seatframewhen y having a seat frame hinged thereto at lts the parts are folded foruse as a chair, Otherwise, any voutward pressure upon the arms would strainr the cables and their conf nections. connectv with projections -27f andv pass on one side to yprovide a'. cushioned and fin having an mver'tible ,seat frame and drop tachingl with seat frame 6-v at corners mediately beneath projections -27- to to lift'arms -22-. v Obviously, Vwhen cables '-2tare under tension to lower arms 22, cables 25- are 'slackened,' and' frame, in combination witha s et of cable 'connections between saidarms and i' ,seat
